Abstract
The use of inorganic additives such as mica in the polyolefin layer of paper polyolefin paper laminates improves the electrical characteristics, gives resistance to discharge, and facilitates reduction of swelling in contact with oil. Accordingly, the present invention provides laminated paper polyolefin paper composites comprising first and second fiber paper layers, and a polyolefin layer comprising an inorganic additive such as mica.
Claims7
A laminated paper polyolefin composite comprising first and second fiber paper layers each laminated to a polyolefin layer containing silicates which impart discharge resistance to said composite.
